Emmasa

Emmasa’s mission is to manage the integrated water cycle in the municipality of Santa Cruz de Tenerife, which includes: collection, desalination, treatment, distribution, sewage, purification and regeneration of water. We offer our clients the maximum excellence in service from an organizational, technological, administrative and operational point of view, and we are proud to contribute to the improvement in the quality of life of the citizens of Tenerife and the entire archipelago of the Canary Islands. The facility has thirteen wells drilled to a depth of 36 meters next to the coast and thirteen submersible pumps extracting water from the sea before the filtering. 

Our desalination plant is a bencmark in the island due to its innovative system. To carry out the desalination process, seawater is first collected from the sea, filtered in sand filters and then it goes through a reverse osmosis process. This procedure uses an energy recovery system in which almost all the energy contained in the brine is recovered. 

The infrastructure has 3 reverse osmosis racks and, for each 100 liters of water that we take from the sea, 47 are destined to the supply of drinking water. Thus, nearly a 60% of the water consumed in Santa Cruz de Tenerife comes from the desalination plant. 

This P3 is currently managed by Sacyr Water.
